The fiscal argument for AI rests on a narrow empirical claim: that even modest productivity acceleration (0.1% annually) compounds into meaningful GDP growth that expands the tax base and stabilizes debt-to-GDP ratios. This reframes AI from a technology adoption problem into a macroeconomic necessity—one where productivity gains aren't optional optimizations but structural requirements for avoiding debt crises. The constraint isn't whether AI can be productive, but whether productivity gains materialize quickly enough and distribute broadly enough to affect government revenues before demographic spending pressures (healthcare, Social Security) overwhelm the budget. This is less a question about AI capability than about timing and the political economy of productivity distribution.
